This species closely resembles P. sesquistnatum, Mars., but 

 differs by the frontal stria not being broi<en, tlie thoracic stria 

 being sinuous before the base, the second dorsal stria is not 

 interrupted near the middle, and the outer margin of the pygi- 

 dium is densely punctuUite. The propygidiuni is without a 

 " transverse train of punctures."

The elytral striation of this species and its facies generally 

 correspond with P. Pavgami^ Le Guillou : the head is, how- 

 ever, more transverse, the lateral tlioracic stria is not parallel 

 to the edge but sinuous, the propygidium is wider and partly 

 smooth ; the pygidium is bifoveolate at the base, witii rather 

 fitie punctures, instead of coarse closely set points ; and the 

 proslcrnal keel is sinuous between the cox£e.
